One of the suggestions that was offered a while back as to how to have
both USB host and mass storage on a Gumstix system was to use two
Gumstix motherboards connected by ethernet or serial.
Given the recently slow timings of ethernet throughput, if you don't
need fast storage and can live with a FAT32 filesystem, might this new
IC be an option?
It provides a FAT16/FAT32 filesystem over a UART (up to 230400 baud) or
SPI, with I2C forthcoming, up to four files open simultaneously. Spark
Fun also has it attached to an SD/MMC card socket here:
Has anyone seen this? Isn't SPI supposed to be faster than those UART
speeds? Is SPI broken out on the Gumstix or daughterboards somewhere?
Could this be hooked up in a relatively straightforward fashion,
ignoring the fact that it wouldn't be exposed as a traditional
filesystem under Linux?
